Not everyone that runs the linux version is here every day, so you won't get instant answers. There ARE a number of messages posted in the last couple of months on Ubuntu issues, so doing a search for "Ubuntu" will probably find your answer.

libcrypto is only supplied by ubuntu as a shared library. Fedora is the same so maybe this is the only option provided by the openssl build system. Otherwise I'm sure MakeMKV would have statically linked this library in order to prevent such version problems. Supporting multiple versions is a headache, so it's understandable that MakeMKV only supports the latest. Fortunately for you, Ubutnu's current LTS release 18.04 does use libcrypto.so.1.1.

So all you need to do is update your system to the latest LTS. Or alternatively, build a local copy of openssl 1.1.
